Steam for Mac Launches Today

The cake is not a lie! Valve’s popular digital distribution client hits Mac OS X today. As we noted a while back, the debut of Steam for Mac coincides with the launch of Steam Play, the cross-platform support that lets play any purchased game on Windows or Mac machines no matter where you brought it.

Portal will be among the first crop of Steam games available for Apple’s machines; new waves will be released weekly. That teleportation-based critical darling uses Valve’s Source game and the company’s promising immediate native OS X support for Source on Macs starting today.

Me, I’m just hoping that I’ll be able to get to that Left 4 Winchester mod for Left 4 Dead that replicates Shaun of the Dead.
